commit 090c351d388da6f19644ea83685419c9db9bb4e1
Author: Marcel Hollerbach <[email protected]>
Date:   Mon Feb 17 13:56:06 2020 +0100

    elementary: use array instead of list for subchildren
    
    this safes in the runtime of elm_test round about 9kb (*).
    Additionally, using a array here is jumping way fewer times arround in
    memory, as we do not need to jump from node to node in a list.
    
    Additionally, this commit replaces a few abort disabler macros with a
    error checking macro. (which cleans the log).
    
    *: explanation: we have round about 600 widgets in elm_test, every
    widget is normally refered once, every list node has 4 pointer, makes
    round about 9600 bytes or rougly 9 KB. So the messured savings are more
    or less explaining the reality.
